INSTALLATION - Continued NOTE If bearings are installed properly, crankshaft will turn freely with all of bearing cap bolts drawn to specified torque. 13. Rotate crankshaft one full turn to ensure freedom of movement. 14. Check crankshaft end play as follows: a. Mount dial indicator with magnetic base (Figure 10, Item 24) on rear of cylinder block with indicator point resting on rear face of crankshaft gear (Figure 10, Item 16). b. Using large screwdriver between main bearing cap and crankshaft counterweight, push crankshaft toward dial indicator with magnetic base. With constant pressure on screwdriver, set dial indicator with magnetic base to zero. NOTE If correct crankshaft endplay cannot be obtained with standard size thrust washers, use 0.005 or 0.010 in. oversize washers. Insufficient end play can result from a misaligned rear main bearing or a burr or dirt on inner face of one or more thrust washers. c. Force crankshaft in opposite direction and note amount of end play on dial. End play must be 0.004–0.016 in. (0.10–0.41 mm) with new parts and maximum of 0.018 in.
